y TESTING DEVICE.

Application filed June so, 1927. serial No. 202,478.

My invention relates to new and useful improvements in testing devices, and more particularly to a device for testing lhollow articles, such, for example, as radiators.

An object of my invention is to provide a device which is of simple construction and elicient-in operation. n

Another object is to provide a device by which defects, whether in the formation,

assembly, or otherwise, in the article to be tested can be easily and quickly detected.

The invention consists in the improved construction and Combination of parts, to be more fully described hereinaftenand the novelty of which will be particularly pointed out and distinctly claimed. r V In the accompanying drawings I have fully and clearly illustrated a preferred embodimentofr my invention, to be taken as 'a part of this specification, and wherein- Figure 1 is a plan view of a radiatorto be tested, with parts broken away, and showing the plug end of my testing device in horizontal longitudinal central section, and a portion of thee head end thereof also in horizontal longitudinal central section;

Fig.` 2 is a view in side elevation ofthe conduit member forming partof the head end of my device;

Fig. 3 is an end view of asleeve support; Fig. 4 is an end view of a cam wheel, and l F 5 is a detailview of the conduit member vfor the plug. v

Referring to the drawings by characters of reference, 1 designates a test fittinghav# ing a Asubstantially lcylindrical support 2 which is internally threaded throughoutA its length. At one end ofthe support`2 is a circumferential flange o r abutment 3. AAt its other end the support 21's of decreased l external diameter, as at 1, to Aform a lshoulder 5. Mounted uponr the vparta is an'operating' member 6 preferably fin the form ofa wheel which is fiXedto' the support 2 'by a key and registering keyways 8, or in any other suitable and well known manner, as

by a set screw, or the like. The wheel 6 is preferably provided with radially rprojecting hand grips 7 which may bedetachable from Wheel 6, as shown, or may be Vformed Lintegral therewith,r if desired. Rotatably mounted on the support2 is'a sleeve 9 which at one end has its internal diameter enlarged, as at 10, totelescopeitheaflange'land form an annular pocket 11 to receive a ball ring and balls 12 which servel as a thrust bearing between support 2 and sleeve 9.Atthe top of-sleeve 9 I preferably provide a boss 13 having an internally threaded socket 14C,y

into which' isscrewed a supporting eye 15| to which may bey attached ra chain, cable, or other member to .support the fitting 1 at the proper Working height from the Hoor.` T his end of the sleeve 9 has oppositely disposed, laterally projecting yokes 16, each having parallel spaced arms 17, 18. Between the arms 17, 18 of each yoke'l isa pivot pin 19 which is fixed in openings 20 which are oppositely disposed in the arms of each yoke. On each pivot pin 19 is freely journaled a fastening 'member 21, preferably in the form of a hook, which has a rearwardly extending end 22 With'a cam surface 23. The sleeve 9-is externally threaded to receive a Cam Wheel 24Ywhich serves as an. abutment and has a conical portion`25 and ears or hand grips 26. Thesleeve 9and camwheel 24 are retained onthe support' 2 by the hub 27 of .thefoperating Wheel 6.

Threaded through the support 2 and in engagement with the internal thread thereof, above mentioned, is a conduit member 29, preferably tubular in form, having a longitudinal conduit or passage 30.` Near the end 3l of member v29, which is adjacent the fastening means 21, isa cup-shaped-flange fast onthe member v29 and having a peripheral baseer flange lproper 32 to form ashoulder,

and a side wall orlaterally projecting ring f 33 extending'ltoward end 31. Seated against thel base 32v and laterally retained by the wall V33,*is a packing' or ysealing ring-Bd, preferably ofv rubber. At the end 31 of the conduit member, the conduit 30 closed by a plate or baille 35, andthe conduit 30 opens between -the vplate 35 and packing means 34 l through an'aperture or hole 36in the under` ting only in the conduit member which is threaded through the support 2. The head conduit lmember 40, shown in Fig. 2, is also preferably tubular in form, having a conduit or passageway 4l and an external thready 427Wh'ieh" engages'the internal thread in a. support 2t, Vivhich is similar lin all re-v spects to the support 2 shown in Fig.

This conduit member 40 is also provided near one end 43 thereof with a cup-shaped flange having a base 44' anda side Wall 45 to .receive apaclting ringor jvasher 4 6. This member 40 however, preferably does notv havea baffle for -the conduit 4l .but is open at itsend 43 in the axial yline of theconduit. At its other end 4S, the member 4() has an elbow 49 Ito which a hose or pipe 'line (not shown) .from a source of supply l.may be connected, asat 50. l-iiiedon the elbow 49 is an eyelet 5llt'o which a supporting member may be connectedto `holdthe fitting at thefdesired height. Ahandle 52 may be attached by threaded-engagement, or otherwise, to `a bos-s 53on theelbow 49.v

The operationlof ymy device xis as follows: A radiator, indicated at 54, Fig. l, or any other -hollow article or body to be tested, havingftwo ports 55, 56, ser-vingas inlet and outlet, is suitably supported, preferably by overhead suspension (not shown), so Ythat it may be properly inspected. The ends 3l, 43, respectively, ofconduit ymembers 29, 40, vare inserted, one in eachoflthe ports 55,556. The jhoolrs or vfastening members 2l of both :the head` andthe -plug fitting, are engaged behind a sectionofthe radiator, see Fig.'1,:and are locked in yposition by turningl each of 'the cam Wheels 24 up on the sleeves *9 until the conical portions 25 abut vhard against the cam Vsurfaces 23. yEach fittingr is novv ylocked tothe radiator' or bodyrunderitest. In order to sealthe joints respectively atports 55,56, the Wheels@ on the headand'thefplug are revolvedin a-cloclrvvise .dir-ectiom and as the internal threads in the supports 2'and 2a are leftfhand, the conduit members 29 and-40 Will be advanced `to press the Washers or packing rings34 and 46tight against the re-v spective ends ofthe radiator. It is-of course evident that f the conduit members themselves will not be rotated, and -that'the supports 2 and 2u will rotate in their sleeves y9. When the valve 38 Ihas been closed, the test lfluid,

,such as water, under desiredtest pressure, is

turned on by opening ayvalve .(-not shown) in the supply -line to the head conduit-14l from the source'of supply.v The fluid will enter the radiator or 'body 54 through the conduit 41 of the head .fitting and be retained therein bythe closedk valve 38. lVhen the article or body under test has been inspected 'for leaks, the 'fluid fromp the source of supply is turned -otf and thel valve 38 opened toy drain tliebody.5'4. Asthe fluid leaves the j radiator yor body, yit .mustpass around and under the baffle 35, which Will cause the current to carry out with it any foreign material, suchas core sand, or the like, which has been deposited Within the radiator along its bottom. The test having beencompleted, the head'aafldfplugl fittings a'rennclainped from the tested article and the article removed, whereupon other artic-l'esmay be tested in turn. i
